I think after the initial shock people calmed down a bit. The reaction right off the bat was pretty fair. Fans here are probably more informed than most, but we aren't scouts. Expecting at least one high end prospect and then getting two pitching prospects who weren't even ranked that high in a pedestrian farm system like the Mets' is obviously going to put a sour taste in most fans' mouths.
People understand Sim could be great, but just because he has the same upside as other top prospects doesn't mean everyone should be happy. There are probably pitchers in every farm system we could talk ourselves into getting excited about, but it doesn't make them outstanding trade targets for Stroman. Sim may look comparable to past Garcia, and might have the same upside, but he hasn't cleared as many hurdles yet and that counts for a lot as far as value is concerned.
I've already convinced myself everything could work out great. Kay has some nasty pitches and I'm intrigued at what he might be able to do. I'd still give the trade less than a B- though for sure and don't blame people for their knee jerk reactions.
